Application filed January 22, 1913. Serial No. 743,432.

To-dill whom #may concern: y f i Be it known that I, RICHARD E. BniiTHoLD,

a citizen of the United States, and resident of Flushing, -in the county of Queens and State of New York, have invented. certain new and useful Improvements in Gras-Igv iiiters, of which the following is a specilication.

ignit-ing devices-for gas burners, the object being to provide means whereby the gas issuing from an ordinary gas yburner will be automaticallyv ignited, and whereby, if the llame be extinguished without shutting off the gas supply, as by blo-wing out said flame, it will be re-ignited and thus the danger'of ari-escape of unburned gas'be avoided.

In my improved igiiiterI employ a catawith' communicating tine platlnum strands in the path of Howing gas,

as is well known the catalytic substance, as, spongy ..platinum, and the plat-inum strands become incandescent, resulting sist combustion, also in die in the vignition. of the gas.

A particular feature of the improvements consists in thel method by which the igniting material is held in the presence of air to asth'e means whereby it is protected from direct contact with the flame which itignites. l

In the drawing: Figure l is an elevation of a vgasv burner with my igniting device applied thereto. Fig. 2 is a side sectional View thereof. Fig. 3 is a bottom plan view thereof. Fig. 4 is a top plan View, and Fig. 5 is a partial side section enlarged.

In said ligures a indicates an ordinary burner tube with burner tip`b. Attached to said burner tube, at the side thereof, as by a band c, is a tube cl, open at both ends. Inserted within tube d isa frame e having 'strung thereon a number of line platinum lstrands f' carrying one or more pellets of catalytic material, as g. A tine pilot tube,

to aV position below the open .tube al. Said pilot tube i has an opening It within burner tube a to receive gas, and an orifice 7a2 to l1 pilot to ignite the larger volume of This invention relates to igniting and reas L, leads from the interior of burner tube a.

permit a tiny jet of within tube /z for the the presence of air gas to ascend axially purpose of reacting, in passing through said tube, upon the catalyticmaterial. The llame produced within tube (l from. the resulting incandescence of said catalytic material and the platinum strands, serves as a gas iss11- ing from burner tip Z), and, obviously,

through recurrent actions the issuing gas will be reigiiited whenever extinguished while the gas flow continues.

It being necessary to protect the catalytic` material 'from the deleterious action caused by flame contact. therewith, and the heat of such contact, I provide a consisting of a transverse bai' z' between gas orilice /22 and the igniter material, said barlserving to spread apart the pilot flame rising from said orifice It?, is prevented' from comin said igniterv material, and whereby the heat zone within tube d extends up at the sides of said igniter material insteadof taking a path axially through said tube`and thereby attacking' said igniter material. The protector bar z may be hollow, as seen, and open to the atmosphere at both sides thereby being cooled through the action of passing air.

A gas igniter comprising a burner-tube, an adjacent open tube parallel therewith, catalytic igniting material supported axially within said open tube, a pilot tube communi` eating from said burner tube to said 'open tube, 'with an orificea-Xially below said igniting material, and a transverse bar between whereby said flame into contact with said igniting material and pilot orifice,l to' Vtioriaiin E. BERTHOLD.
